Arrays, Lists, Stacks and Queues:
1) Write C++ code to reverse a singly-linked list L using only a constant amount of additional storage and no recursion. Assume the list object has a head pointer _head and consists of Node objects; a Node object has a pointer Node* _next

Code:
#include<bits/stdc++.h>
using namespace std;
// Structure to store a linked list Node
struct Node
{
int value;
struct Node *_next;
};
void
push_front (struct Node **_head, int value)
{
struct Node *new_node = (struct Node *) malloc (sizeof (struct
Node));
new_node->value = value;
new_node->_next = *_head;
*_head = new_node;
}
// reverse linked list iteratively
void reverse_list (struct Node **_head)
{
struct Node *previous = NULL;
struct Node *current = *_head;
// iterate through the list
while (current != NULL)
{
// store next of current in next
struct Node *next = current->_next;
// move the current node onto the previous
current->_next = previous;
previous = current;
// process next node
current = next;

// set head pointer
*_head = previous;

Answer all questions 1- in circular singly linked list, previous pointer of the first node points to which node A. First node B. Itself C. null D. Last node 2- Which of the following is NOT an applications of linked lists? A. Implementation of stacks and queues B. Dynamic memory allocation C. Manipulation of polynomials D. Keeping people at home during epidemics like corona virus 3- In a circular singly linked list? A. Components are all linked together in some...
Test ADTs: Linked Lists, Stacks and Queues (Python and with proper indentation for better understanding please). Create a program that will choose 30 objects with an attribute of random number between 1 and 100. Place each object it in a queue. From that each object will exit the queue in the order that it entered two waiting stacks. Sort those stacks and create two doubly circular linked lists from those stacks. Merge those lists into one doubly circular linked list....
Describe in detail an algorithm for reversing a singly linked list L using only a constant amount of additional space and not using any recursion.
Write a C# function bool HasCycle(Node head) that detects a cycle in a singly linked list. It must return a boolean true if the list contains a cycle, or false otherwise. HasCycle has a reference to a Node object, that points to the head of a linked list, as parameter.
write a java program implementing stacks using arrays. (not with linked list)
Write a program void reverse_list(list **l)in pseudo-code or C++ to reverse the direction of a given singly-linked list. In other words, after the reversal all pointers should now point backwards. Your algorithm should take linear time. The node of this singly-linked list is defined as typedef struct list { item_type item; struct list ∗ next ; } list; void reverse_list(list **l){ } Remark: 15 points for completely correct. 10 points for correctly reversing the list with minor errors.
C# code Arrays and Linked Lists: Write C++/Java/C#/Python code to declare an array of linked lists of any primitive type you want. (Array of size 2020) (This could be based on MSDN libraries or the lab) – you do not need to instantiate any of the linked lists to contain any actual values. Paste your code for that here (this should only be one line) Based on your code or the lab from 4 or your doubly linked list from...
Please fill in this code to reverse a linked list: (written in C/C++) #include #include #include using namespace std; /* Link list node */ struct Node { int data; // your code here }; /* Function to reverse the linked list */ static void reverse(struct Node** head_ref) { // your code here } /* Function to push a node */ void push(struct Node** head_ref, int new_data) { // your code here } /* Function to print linked list */ void...
***CODE MUST BE IN C++*** Using the linked list in "basic linked list" which has a STRUCTURE for each node, write FUNCTION which starts at the head and outputs the value for each node until the last node is reached. Note: your function should work with the structure that is in this program. Please do not use the example which is for a class, but this example canbe helkpful. Also note that the function must work no matter how many nodes...
[C++] Create three functions for a singly linked list: - Function 1: Insert a string into the linked list - Function 1: Insert a node after a given node (Node* curNodeptr, Node* newNodePtr) - Function 2: Delete the node passed to it by a pointer, it will take in the head and curPtr '(Node*, Node*)' struct Node{ string data; Node *next; };
